To use this cap, simply adjust the buckle closure to fit your head comfortably. It's perfect for wearing during rugby games or casual outings. When it comes to care, always hand wash it. After washing, pat it down with a towel to get rid of excess moisture, but be careful to keep the hat's shape. Then, dry it on the counter. You can dry it on top of a container to help maintain its shape. Remember, don't machine wash or dry it to avoid damaging the 3D embroidered logos and the overall quality of the cap.
